Hi there. I have a radgridview inside a radpanel (radpanel has autoscroll=true). Whenever the radgridview expands & is scrolled down upon - the back part of the panel contains horizontal lines, if I click near them they disappear. Does anyone know what is causing this?
Thanks!
Thanks!

Hi Paul R.,
This is a known issue with the custom GDI painting and AutoScroll controls which is the case with RadControls for WinForms. The blue lines you are seeing are caused by the RadPanel's border so removing the border can fix the issue:
If you do not want to remove the border, you can use the RadScrollablePanel control. Just set the AutoScroll property to true and when any control on it exceeds its bound, the scrollbars will be displayed. In addition to this, you will also get a fully themeable scrollbars.
I hope this information was useful. If you have any further questions, do not hesitate to ask.
Kind regards,
